An Hsp70 promoter drives expression of an intronless Dhyd\Minos\Ths.PF gene.
Left hand repeat of Dhyd\Minos is replaced by the Hsp70 promoter.
456bp XbaI-XmnI fragment of Hsp70 promoter and 206bp of untranslated leader sequence replace the 5' inverted repeat of Dhyd\Minos\T.
Dhyd\Minos transposase gene is under the control of a heat shock promoter.
Used as a Dhyd\Minos transposase source assayed in the D.melanogaster genome.
A defective Dhyd\Minos transposon that is inserted into the D.melanogaster genome is stable in the absence of Dhyd\Minos\Ths.PF but is mobilised at relatively high frequencies in the presence of transposase.
